His wife at the time of his death was Dorothy Reisch. I have no knowledge of why she went by that name. But, when he signed the deed of his cono over and when she eventually sold it, that is the name she went by. Later docs indicate they were married at his death. The FL public records do not give any indication there were children involved. But, who knows? You could request his death certificate. That could lead you to a funeral home. They might have some extra records.
I did not locate a death for Dorothy, or any other records for her.
Good hunting,
Frank
